离心泵叶轮轴面流道约束建模及其初值计算

Constraint modeling for the meridian passage in centrifugal impellers and its initial parameters

提出了描述离心泵叶轮轴面流道的通用约束模型 ;给出了获得满意初始模型的数值解法 .因此避免了“内切圆校正法”中型线调整和面积计算等方面的不足 ,为离心泵叶轮CAD提供了一种有效的轴面流道建模方法 .

A general constraint model for describing the profiles of centrifugal impellers is presented and an algorithm for finding good initial parameters of the model is provided based on the numeric solution. Without inconvenience in shape alteration as well as inaccuracy in area calculation in traditional design methods, an effectively constraint modeling method of the profiles in CAD is obtained.
